Turns out that a lot of people I knew posted huge life updates that I completely missed out on. I asked them why they didn’t tell me and they were confused. They said the posted it on social media. I can’t speak for everyone, but I know a lack of social media meant that I have lost touch with old acquaintances completely. I have a few close friends and that’s it.
Maybe that’s an ok tradeoff to make, but it’s worth knowing that before getting into it.
Seeing people's updates on a wall isn't truly keeping up with friends. Keeping up and staying in touch requires consistent deliberate effort from both parties, via phone calls, messaging, and seeing each other in person. If you're not doing that with someone, then yeah, learning about life updates when you actually chat and catch up just makes sense to me.
